LH540205 Datasheet PDF - Sharp Electronics

Data words are read out from the LH540205’s output port in precisely the same order that they were written in at its input port; that is, according to a First-In, First Out (FIFO) queue discipline. Since the addressing sequence for a FIFO device’s memory is internally predefined, no external addressing information is required for the operation of the LH540205 device.
